FEAT-FUEL PRODUCTION.

Application led September 20, 1924. Serial No. 738,789.

.[his invention relates to peat fuel and and es cially to the handling and preparation o same 1n the production of a commercial product.

The principal object is to provide an economical and practical method of transforming peat, as found in its natural state, toa commercial fuel.

Another object lis to economize in the use of fuel for drying purposes.

Still other objects and advantages will appear in the further description of the invention.

The accompanying drawing, forming part of this application, in which like reference characters indicate like parts; represents, 1n

a diagrammatical way, one embodiment of the invention, the same being partly in section and partly broken'away.

In carrying out the invention we employ a heating furnace, indicated at`1, the combustion chambenbeing shown at 2, the same being fed by a suitable form of dust fuel such as pulverized' coal, or, if desired, portions of'the product resulting from the employment of the invention may be used, the

uel being fed through the pipe 3 and nozzle 4- which latter projects within the combustion chamber, and common in the art. so As aA means of draftfor the combustion chamber 1 we provide a pipe 5 having installed therein the suction fan or blower 6 ,operated by a suitable motor indicated at 7, the discharge from said fan being indicated at 8 enterlng the upright storage bin or tank 9. Intermediate of the fanor blower 6 and the combustion chamber 2 is installed a branch pi e 10 leading from the hopper 11 4QI of a suita le macerator 12, intowhich dewatered peat may be fed b the endless belt or other means as indicate at 13.

A screw feed indicated at 14 is installed'- ipe 5 and subsequently into the may be of any desired construction, at 17, in l the extreme end of the combustion chamber from the nozzle 4 for the separation of the sparks or heavy granular material that mi ht occur within the combustion chamber so t at the same may not be carried through into the fan 6, though it is evident that this may be dispensed with or varied in respect to the fuel being used, and the latter may be any of various forms of gas or oil if so desired. The storage tank or depository 9 is pro vided with an upright stack 18 through which any remaining dampness or unutilized smoke or gas may be discharged, or, if considerable heat is found to escape from said discharge under certain conditions the same may be used over again in the further dryinvof subsequently treated peat.

e do not consider it essential in the disclosure of this invention to describe the manner in which the peat is originally treated or dewatered, as the same is immaterial and it is well known that various methods of such accomplishment are resorted to; in fact, in many instances, peat is found in quite granular and more or less dried form which may be fed directly to the macerator 12.

Our present invention resides particularly in `the passing of finely granulated peat and hot air through a fan and thence to a place of deposit for a final drying of the peat to a proper state for fuel pur oses, together with the novel arrangement For utilizing all of the heat and other products of combustion during such process of finally drying the peat.

It is to be noted that by passing granular fuel substances through a fan and thoroughly commingling same with the products of combustion of a foreign fuel which may give off more or less unconsumed products, the latter may become incorporated with the peat and thus saved for future consumption. l

Having thus describedour invention, what we claim and desire to secure by Letters Pat'- ent is: 4

A peat drying unit of the character descr1bed comprising a combustion chamber, a

bustion chamber and the de ository for conveying the products of com ustion fromthe depository located remote from the combustion chamber, a fan intermediate of the comformer to the latter, and means for supplythe products of combustion from the former ing dewatered granular .peat tothe products to the latter, and means for supplying del0 of combustion en route to the depository. watered granular peat to the products of 2. A peat drying unit of the character decombustion en route to the depository.

5 scribed comprising a combustion chamber, a In testimony whereof we hereunto affix oul` depository located remote from Said chamslgnatures. ber, means intermediate of said chamber LEONARD BROVN. and the depository for forcibly conveying WALTER L. BROWN.
